How Can Deer See in the Dark?

This strolled across my Facebook feed this morning, and I thought it was worth a post here.
It was posted to the Hunt Florida Facebook feed, which belongs to Florida’s FWC, which is tasked with managing Florida’s wildlife. Anyhow, here’s what it says about the night vision of whitetail deer:
How deer see in the dark
Not only do deer have a wide field of vision and an amazing ability to detect movement, they also have special adaptations for low light vision. Their eyes have a membrane called the tapetum lucidum, which reflects like a mirror and essentially doubles available light. Plus, deer are likely more sensitive than humans to the blue to blue-green portion of the light spectrum, which helps them see better at dawn and dusk.
And I gotta tell you, from a hunter’s perspective, dawn and dusk are tough times for a deer hunter. They can see well, but we cannot.
That’s when high-quality optics can help. Get yourself a good rifle scope if you don’t want to find yourself wondering whether that deer is legal or not as day fades into night.
For more information on whitetails, the FWC has published a profile on their website; check it out when you get the chance.
